Systems of ordinary differential equations are a common object of study in various
scientific disciplines. Many exact solutions to such systems can be found in the
handbooks [1]}, [2]}. The article [3]} presented partial solutions
to a class of systems of first-order nonlinear ordinary differential equations with
homogeneous polynomial right-hand sides. The current note deals with more general
(than in [3]}), quasi-homogeneous systems of first-order nonlinear ODEs as
well as homogeneous systems of second-order nonlinear ODEs. It presents several exact
solutions to these systems in terms of elementary functions.
